COIN-CONTROLLED VENDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 533,966, dated February 12, 1895.

I Application filed May 10, 1894:. Serial llo. 510,682. (No model.) 7

To all whom it may concern:

Be it known that I, CHARLES A. SfIATTUoK, of Maiden, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Coin-Controlled Vending-Machines, of which the following is a specification.

This invention relates to coin-controlled vending machines and one object is to provide improved means for preventing opera-.

tion of the machine by a spurious piece inserted in place of the proper coin.

Another object is to provide improved delivery mechanism insuring against the issu- 5 ance of more than the specified number of the articles on sale or amount of the commodity.

Another object is to provide an improved construction of inclosing casing permitting ready access to the delivery mechanism and arranged to be effectually closed by the looking of the main door.

To the above ends the invention consists in certain novel features of construction and combinations of parts recited in the appended 2 5 claims and specifically described hereinafter. The accompanying drawings illustrate a construction embodying the invention.

Figure l showsa front elevation of the machine With the door thrown back and the slides taken out. Fig. 2 shows a side eleva' tion of the internal mechanism with the casing in section and the door closed. Fig. 3 shows in elevation on an enlarged scale certain devices for arresting and rejecting spuri- 5 ous pieces' Fig. 4 shows a section on line'- 4C 4 of Fig. 3. Fig. 5 shows a similar view to Fig. 4: with the parts in a different adjustment. Fig. 6 shows a section on line 6-6. of Fig. 3. Fig. 7 shows the delivery mechanism in side elevation on an enlarged scale. Figs. 8 and 9 show sectional views of the same illustrating the operation of certain cams. Fig. 10 shows an elevation of the opposite side of this delivery mechanism.

5 The machine here illustrated is specially designed for vending commodities in the form of cakes as for example, cakes of chocolate, such articles being stacked in vertical chutes or magazines, a, two of which are here shown supported side by side in the vertically ex-' whose base or lower portion, b, contains delivering mechanism hereinafter described. The portion, 1), of the casing is closed by a hinged door, 19 on the inner side of which are supported certain devices for conducting the coins to the delivery mechanism and for disposing of spurious pieces.

A slotted coin-receiver, c, is fastened to the 1 door and protrudes from the edge of the same and an inclined coin-chute or way communicates with the slot of said receiver and is of the following construction: Its upper side is composed of bars, 0'," with a space between them for the coin to run in, and said bars have right angle portions, 0 forming the end of the chute. The lower side of the chute is composed of a bar, 0 formed with trunnions which journal in the receiver, 0, and the end portions, 0 of the bars, 0', so that said bar 7o 0 may tilt laterally for a purpose hereinafter explained. Said bar, 0 is grooved in the upper edge for the coin, and cut away at its lower end, as shown at c, to allow the coin to drop out of the chute when it arrives at the 7 5 Adjacent to the bar; 0 a permanent magnet, (1, is fastened to the door and the bar is cut away in its rear side so that the poles of the said magnet may form one side of the groove in the bar, at this part and be encountered by a piece passing along the groove. This magnet is designed to arrest a spurious piece or disk of iron or steel by attracting the same, and hold it so arrested until it is ejected from the chute by the introduction of a coin into the receiving slot. A piece of wire, e, is fastened to the bar, 0 and shaped rectangularly so as to embrace the poles of the magnet. Upon tilting the said bar this wire frame, e, will act against a piece arrested by the magnet and eject it from the chute. Thus a spurious piece cannot pass to thedelivery mechanism.

The tilting of the bar, 0 is effected through the following means: A vertically swinging lever, f, is pivoted intermediate of its ends to [03 one of the bars, 0, and its forward end carries a pin, f, projecting across the receiving slot and occupying a side slot in the receiver, 0. The opposite end of said lever has a lateral arm, f which is connected by a rod, f with a lateral projection, f, on the bar, 0. A spring, f presses against the lever arm, f and holds the pin,f', down in the path of a coin in the receiving slot. Upon pushing a coin as, 2, into said receiving slot it encounters said pin and raises the same thereby depressing the opposite end of the lever and tilting the bar, 0 away from the door. The spring, f returns the bar, 0 to its normal position as soon as the coin passes the pin and before it reaches the bar, so that the latter will be ready to receive the coin.

The delivery mechanism will next be described.

Gates in the form of hinged plates, g, and g, extend under the lower ends of the magazines, a, and the stacks of cakes, 3, rest upon them. These plates are hinged at 9 to uprights, 9 on a frame, 9 which rests on the bottom of the casing and supports a springmotor or clock movement, the letter, h, designating the main spring thereof, h, the gears, and, 7L2, the escapement. The plates, 9, and, g, have supportinglegs, g and, g, the front edges of which are inclined as shown so that they serve as cams to be acted on as hereinafter described. Levers, i, and, i, pivoted to the frame, 9", carry rollers, t supporting the gates, g, and, g, by engagementwith the bottom edges of the legs, g and, g. Springs, 2' impel the levers in a direction to move said rollers under the lowest portion of the legs and hold the gates up close to the magazinechutes so as to close the same. A shaft, 70, of the spring-motor has affixed to it cams, i, and, i arranged to act on rollers, i and, 2' on the levers, t, and, 7;. These cams are doubleended, as shown, so thatin one complete revolution of the shaft each one acts twice on the lever to move it outward and permit the gate to lower. The said cams are set at right angles to each other on the shaft so that they do not both act at the same time on their respective levers, but alternately during quarter revolutions of the shaft. It will be seen that outward movement of either one of the levers imparted to it by the cam takes the roller at its upper end out from under the bottom of theleg on the gate it is supporting so as to allow said gate to lower byits own weight as the roller progresses outward on the inclined front edge of the le When the cam has passed the roller it engages, the lever is returned by the spring,

' i and by the roller at its upper end acting having radial shoulders, n, at four equidistaut points. A detent-arm, n is pivoted on a post projecting from the frame and formed with a shoulder, a, for engagement with the shoulders, n, of the disk, at, a spring, a, exerting itself to produce such engagement. The outer end of the arm, n carries a plate, or, below the lower end of the chute, a, so that a coin falling through the latter will drop upon said plate and by the impetus it has gathered in its descent, move the arm, n downward against the stress of the spring, a and disengage its shoulder from that of the disk. Upon the disengagement of the detent from the disk the motor immediately starts, and one of the gates is opened and a cake drops out and down the delivery chute, and the gate closes again. This takes place during a quarter revolution of the shaft, 70, at'

the end of which movement the motor is stopped, for, after depressing the detent-arm the coin immediately slides off the plate, 1r, by reason of the inclination thereof produced by its downward movement, and the spring, or, returns the detent against the periphery of the disk so that its shoulder is standingin the path of the next radial shoulder of the disk. The coin will be received in a suitable till or box.

The provisions for preventing more than one cake issuing at a time from the magazine will next be described.

It will be observed that each of the magazine-chutes, a, is preferably open at the front with flanges at each side to confine the cakes. At the lower end of each chute, a bar, 0, extends across the front, and the rear side of the chute opposite this bar is cut out to accommodate a stop device which acts against the next lowest cake and by pressing it against the bar, 0, blocks the stack of cakes while the gate is open so as to prevent escape of any but the lowermost one.

The stop-device above referred to is in the form of a lever, 0, pivoted at, 0 to the frame, and its upperarm composed of a resilient piece, 0 whose upper end is bent over and toothed or serrated, as shown at, 0 to take a hold in the cake. A spring, 0 exerts itself to retract the upper end of the lever. The lower end of the lever carries a roller, 0, which is arranged to be acted upon by a double-ended cam, 0 on the shaft, 70, to move the upper end of the lever against the cake. The two stop-levers act at different times and the cams, 0 are therefore set on the shaft at right angles to each other.

\Vhen the motor is tripped, the stop device over the gate which is lowered, is thrown forward against the next lowest cake of the stack and the escape of any but the lowermost cake is prevented. After the gate has closed the stop is retracted so as to allow the stack of cakes to lower.

The two stop-levers are alternately worked as are the two gates.

The bottom or base portion, 1), of the in- IIO closing casing has its front side closed by a sliding board, q, havingbeads engaging vertical grooves in the sides of said base-portion.

. Said board, q, supports the delivery chute, 1%,

the sides of which are fastened to the board and the bottom of which extends out through an opening in the board and has an upturned lip, m, to stop the'descending cake and hold 'it where the vendee can readily extract it.

An inclined plate, 4", is preferably fastened to the motor frame, and the upper end of the delivery chute rests upon it.-

7 an upstanding flange, s, at its upper inner side which when the board is in place is flush .with the front edges of the sides of the vertically extending portion of casing. The door, shuts against this flange. It will now be seen that when the door is locked the two slides, s, and, q, are also looked. When the door is opened the slides can be readily removed and access had to the delivery mech-' anism for purposes of repair or adjustment.

It is evident that the invention is not limited to the particular embodiment here shown but may be carried out by other means.
